7Kw ~18KW Split System Air Energy Heat Pump Suitable for Cold
Weather
Features
It adopts Copeland compressor and operates in an ultra-wide range.
◆The reverse flow circuit is arranged to ensure the subcooling
degree of the refrigerant, which effectively improves the heating
efficiency and the normal operation of the unit at low temperature.
◆ It operates under ultra-low temperature conditions and can work
normally at -25 °C.
◆ Energy efficiency guarantee, solve the common problem of low
temperature, no heat, low energy efficiency.
◆It has automatic anti-freeze function to prevent components such
as water pump and water pump from being cracked.
◆The performance is steep under the cold, safe and reliable, and
the heating capacity under -10 is increased by 20 °C, which is more
suitable for cold regions
